ScalpelAoto has a rather simple weapon that he uses for fighting you may think this is just a normal weapon, but when aoto fuses his chakra into the weapon the scalpel that small weapon becomes a sharp bladed killing weapon. Also to note this scalpel has poison on the tip of the blade part, so when a person is cut there going to become poisoned.

Poison thornsThis weapon here comes from a small plant that aoto picked before he lift the clan, see these thorns as poisoned at the tip so if hit in the right spot, the poison wont take long to take its effect on the enemy.

Paper bomb'sSimple weapon indeed a small explosive piece of paper, that some times aoto would attach to his weapons when he throws it at people.
